New Delhi: The Congress yesterday came down heavily on Prime Minister Narendra Modi in the wake of imposition of President's rule in party-ruled Arunachal Pradesh declaring that it would the decision 'fight tooth and nail'.

"Sun rises in India's east. The BJP, however, eclipses Constitution's ethos by imposing Central rule in Arunachal. Federalism trampled by Modiji. Republic's founding principles of Democracy & Federalism gutted by Modiji on Republic Day! Will fight Central Rule in Arunachal tooth and nail", party's chief spokesman Randeep Surjewala said in a series of tweets.

His tweets came within hours of President Pranab Mukherjee approving Union Cabinet's recommendation to impose central rule in the northeastern state.

Earlier, another Congress spokesperson Tom Vadakkan said, "This is murder of democracy... The matter is sub-judice and government has acted in haste. It is a clear-cut insult to the highest court of the land. Democracy has been murdered".
